The turning angle sensor 4 is used for detecting the turning angle of the handle and outputting a turning angle signal related to the turning angle of the handle to the meter device 5. In the present embodiment, the turning angle sensor 4 may be, for example, an acceleration sensor or the like.
The wheel speed sensor 3 is used for continuously outputting pulse signals to the meter device 5 from a navigation start point.
In this embodiment, the meter device 5 includes a meter host display 50, a meter host 51 electrically connected to the meter host display 50, a meter panel display 52, and a meter panel controller 53 electrically connected to the meter panel display 52 and the meter host 51. The wheel speed sensor 3 is electrically connected to the instrument panel controller 53 only, so that the pulse signal sensed by the wheel speed sensor 3 is transmitted to the instrument panel controller 53 first, and then the instrument panel controller 53 transmits the pulse signal to the instrument host 51. The turning angle sensor 4 is electrically connected to the instrument panel controller 53 and the instrument host 51 at the same time, so that the turning angle sensor 4 can output turning angle signals to the instrument panel controller 53 and the instrument host 51 at the same time.
As shown in fig. 2, in the present embodiment, the dashboard display 52 is divided into a left area portion and a right area portion, and is mainly used for displaying information such as the number of mileage traveled, the voltage of the battery, the wheel speed, the oil level, etc., and the dashboard host display 50 disposed in the central area can enter a connection mode according to the operation selection of the operation buttons (not shown) by the user. In the wired mode, the meter host 51 can be wired or wireless to the portable device 6 and cause the meter host display 50 to present smart functions such as speed per hour, time, weather, smart compass, notification and car finding. In addition, the meter host display 50 can enter a meter panel display mode according to the operation selection of the operation key by the user, wherein the meter panel display mode can be operated by the user to select the meter panel information such as the accumulated mileage, the single mileage accumulation, the fuel amount, the front and rear tire pressure, the battery voltage and the like displayed on the meter panel display 52.
As shown in fig. 1, in the present embodiment, the meter host 51 includes a processing module 511, a wireless connection module 512, and a storage module 513 for storing a firmware program 5130 as an Operating System (OS) of the meter host 51. The processing module 511 is electrically connected to the meter host display 50, the wireless connection module 512, and the storage module 513. In this embodiment, the wireless connection module 512 may be, for example, a bluetooth module, a Wi-Fi module, or a Near Field Communication (NFC) module, and the meter host display 50 may be, for example, a liquid crystal display.

Referring to fig. 1 to 3, an embodiment of a navigation method for improving navigation accuracy by using information of a vehicle itself according to the present invention includes the following steps. First, as shown in step S91 of fig. 3, the wheel speed sensor 3 continuously outputs a pulse signal to the meter device 5 from the navigation start point, and the turning angle sensor 4 outputs the turning angle signal to the meter device 5.
Next, as shown in step S92, each time the processing module 511 of the meter device 5 receives a predetermined number of pulse signals, the processing module 511 of the meter device 5 calculates a predetermined driving distance according to the predetermined number of pulse signals and the turning angle signal. In the present embodiment, the predetermined travel distance is set to one metric. Assuming that the outer circumference of the tire of the vehicle 1 is 90 cm, and that the wheel speed sensor 3 continuously outputs 9 pulse signals during one rotation of the tire, which corresponds to 10 minutes of forward movement of the vehicle 1, the wheel speed sensor 3 outputs one pulse signal to the processing module 511 of the meter device 5, so that the wheel speed sensor 3 outputs 10 pulse signals to the processing module 511 of the meter device 5 every time the vehicle 1 advances one meter, i.e., the predetermined number is 10. Thus, the processing module 511 of the meter device 5 basically calculates the predetermined travel distance according to the predetermined number of pulse signals, so that the navigation accuracy of the present invention can be accurate to one meter, and thus much more accurate than the conventional positioning system (such as GPS, etc.) with a positioning error of up to about 10-20 meters.
As for the turning angle caused by the handle of the vehicle 1, since the vehicle 1 may not actually advance along the center line of the road when traveling along the road corresponding to a navigation path from the navigation start point, but the handle of the vehicle 1 may be turned due to various road conditions, the processing module 511 of the meter device 5 may calculate the relative traveling distance of the vehicle 1 with respect to the navigation start point more accurately by taking the turning angle caused by the handle into consideration in the present embodiment.
Next, as shown in step S93, the meter device 5 transmits the predetermined travel distance to the portable device 6.
Next, in step S94, the processing unit 61 of the portable device 6 calculates the real-time position coordinates of the portable device 6 on the navigation path according to the predetermined driving distance and the navigation path.
Next, in step S95, the processing unit 61 of the portable device 6 transmits a navigation map 500 including the real-time position coordinates and the navigation path to the meter device 5. Then, as shown in step S96, the meter device 5 displays the navigation map 500 with its meter host display 50, as shown in fig. 2.
Referring to fig. 4, in the first variation of the present embodiment, the meter main body 51 is electrically connected to the meter panel controller 53, the wheel speed sensor 3 is electrically connected to the meter panel controller 53 only, and the turning angle sensor 4 is electrically connected to the meter main body 51 only. Therefore, the pulse signal sensed by the wheel speed sensor 3 is transmitted to only the instrument panel controller 53, and then the instrument panel controller 53 transmits the pulse signal to the instrument host 51. The turning angle signal sensed by the turning angle sensor 4 is transmitted only to the meter main unit 51.
Referring to fig. 5, in a second variation of the present embodiment, the meter main body 51 is electrically connected to the instrument panel controller 53, and the wheel speed sensor 3 and the turning angle sensor 4 are both electrically connected to the instrument panel controller 53. Therefore, the pulse signal sensed by the wheel speed sensor 3 is transmitted to only the instrument panel controller 53, and then the instrument panel controller 53 transmits the pulse signal to the instrument host 51. Similarly, the turning angle signal sensed by the turning angle sensor 4 is transmitted to the instrument panel controller 53 only, and then the instrument panel controller 53 transmits the turning angle signal to the instrument host 51.
Referring to fig. 6, in a third variation of the present embodiment, the meter device 5 includes only the meter host 51 and the meter host display 50, and no instrument panel controller and no instrument panel display are required. That is, in the present variation, the meter host 51 can have all functions of the dashboard controller, and only a single meter host display 50 can display all the contents to be displayed. The wheel speed sensor 3 is electrically connected to the meter main unit 51 and transmits the pulse signal to the meter main unit 51, and the turning angle sensor 4 is electrically connected to the meter main unit 51 and transmits the turning angle signal to the meter main unit 51.
In summary, the navigation accuracy can be accurate to one meter by the cooperation of the portable device 6, the meter device 5 of the vehicle 1, the wheel speed sensor 3, the turning angle sensor 4 and other software and hardware components, so that the navigation accuracy is much higher than that of the conventional positioning system (such as GPS) with the positioning error of about 10-20 meters, and the purpose of the invention can be achieved.
The foregoing is illustrative of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims and their equivalents.
